Product Description

The Surefire X300 Ultra delivers a stunning 500-lumen beam focused by a precision TIR lens. Its specially selected high-performance LED is biased slightly towards the yellow-green part of the spectrum to which the human eye is most sensitive. This combination of extreme output and optimized off-white light color increases perceived light available for the user, creates a brighter surround beam for enhanced situational awareness, and increases the blinding effect on an opponent’s dark-adapted vision. The X300 attaches to the Picatinny and Universal rails found on many handguns, and will fi t many popular rail-less handguns by using Sure Fire's MR adapter mounts. It features integral one-finger ambidextrous switching and can be equipped with Sure Fire's optional DG handgun grip switch. Also attaches to the Picatinny rails on long guns, and can be activated via optional remote switches.

After trying this fellow out on both a G19 and an AR15, I have to say it far exceeds my expectations. I played around with some other weapon lights but this guy is in its own class.

It mounts on my G4 G19 like it was designed specifically for the gun. A rock solid perfect fit. On the AR, it clings fiercely to a short rail I mounted on my Magpul handguard. Again, a smooth integrated look and feel.

So is it too much of anything? Only price, perhaps, but given that it works fine as a single-output 500 lumen flashlight, I guess that makes it about $50 more than a regular Surefire.

There are a couple ways to judge the brightness since that is a question often asked. For starters, is there too much light? Is that possible? Of course it is, but in this case, unless you are staring into your own weapon light, or hit a mirror at point blank, the amount of light all good for several reasons, and an integrated light makes it even better. But keep in mind this light is ONLY 500 lumens. There are many far brighter lights out there, so while high lumens for a small weapon light, it is still just a flashlight.

First, once you crank on a weapon light of any flavor, you are kissing your night vision goodbye. Once gone, you then need the light to see so the winner here is more light.

Second, when someone is on the business end of this light, it helps prevent the good guy from being an easy target. I tried it myself. When facing down this light, you cannot see squat! Just a huge ball of light far larger than a person. And that's if you have good eyes. Add any maladies to the eyes and it only gets worse with flair etc. Lesser lights make nice targets for the enemy.

This is the most intense light I have ever owned I mounted it to my M-4 carbine and it is totally amazing I live out in the country and I have a small pasture behind my house my dogs like to bay pigs at night and this light illuminates the entire pasture making it quite easy to eliminate pesky pigs or any other varmint that may come around either 2 or 4 legged.I cant think of anything negative to say about this fine illumination tool. I highly recomend purchasing this light its worth every penny you pay for it between this light and my Surefire Fury PX-2 Tactical I feel like I could light up the world.02/09/13 I ordered one for my wifes Valentines gift for her M-4 and she loves it.4-13-13 Heres an update I just bought 2 more of these AWESOME LIGHTS one for my G-19 and one for the wifes G-19 These must be the best weapon lights on the market they are so impressive I havnt seen anything that compares to Surefires Quality or Dependability!!! If you own a weapon with a picatinny rail and dont add one of these lights to it you are missing out.

The previous Surefire light (x300) was a very high-quality light, as you can see by the many high reviews. This one (Surefire x300 Ultra) is basically the same, but MUCH brighter. (besides the slight bevels on the end of the light, which look cool, but do nothing that I can tell).

Pros:-incredibly sturdy feel-easy to mount-easy to install/replace batteries-comes with the 2 required batteries-SO bright (500 lumens vs the previous 170)-price - though $299 seems a pretty hefty price for a light, when you consider the previous version (170 lumens) is $275, I'd consider paying only an additional $24 dollars for 500 lumens to be a great deal.-ambidextrous (can use with right or left hand easily as it has a switch on both sides)-still fits in the same holster as the x300

Cons:-personally, I would rather the left switch be a hold-down-on switch instead of a push-and-stay-on switch (then keep the right the same as it is)-price - yes, I know I put this in the pros too, but - it is still $300 for a light. Do I regret paying it for such a sturdy, bright, great light? Absolutely not.

Side note: I read some online questions similar to: "Is it so bright it blinds you when bouncing off a nearby wall?"...etc. This isn't a problem. While it IS incredibly bright, at no time did I feel its bounced light caused any issues.

I've been using the Streamlight TLR-1 and TLR-2 for several years now. I've also owned Insight lights and some generic Chinese lights (which I wouldn't recommend on a weapon due to reliability). There are some things I've liked about the Streamlights, and some things I thought needed to be improved. After seeing so many light bearing holsters that only fit the X300, I decided to check it out. Right now I'm very happy I did. Here is what I've noticed in owning the two lights, hopefully this can help you in your decision to purchase the right light for your application.

Here's what I like about the Surefire:

- It's bright, and is every bit of 500 lumens. I compared it to some CREE lights I have, and it had no problem hanging with all of them. The spill and color of [white] light is perfect in my opinion.

- In order to get momentary light, the flip switch works like a pressure switch. Just apply forward pressure on it and you get white light. It's hard to say whether this could cause a light AD (accidental discharge) and be undesirable... but so far I like it compared to the Streamlight.

- There is no screw to mount this to the rail, it's a spring under the rail platform - just pull down on the platform on each side and slide it onto the rail. The downside is this -- if your picatinny rail doesn't have an open end, you're not getting this light on it. The Streamlight's screw is annoying to me at times (because it comes loose while shooting), but it allows the light to be mounted without having to slide it on.

- This light is smaller and slightly lighter than the TLR lights.

One thing I don't like about the X300:

- It came with the universal mount on the light, out of the box.Read more ›
